It is generally safe as the updater has been trained to ignore kernel updates, which would indeed render emc/linuxcnc in operable. I have been installing all the updates as they become available, and ANAICT, its all been fine. Bear in mind though, that if you actually go wandering through the software listing synaptic can show you, you will find newer kernels, but you must resist the "Oh look, a pony" syndrome. I haven't found anything else that seems particularly dangerous though. I have the livecd installed on my laptop that I often use as a code generator, and as a previewer, but rather than running linuxcnc on the lappy, I ssh -Y into the actual machine and just use the lappy for a remote display. For that to work I had to install the latest kernel on the lappy else the wifi didn't work that I use for the remote linkage. On the lappy, the ability to run linuxcnc on it is moot as it has no parport facilities anyway. To summarize, as long as you don't install any new kernels that don't have an RTAI extension, you should be good to go.
